What is a deposit invoice and how to create one
TL;DR, the essentials
- A deposit invoice is a full, legally valid invoice issued when a customer pays part of the total before the goods are delivered or the work is completed.
- It should be clearly marked “Deposit invoice”, carry a unique sequential number, reference the original quote or order and break down the deposit net, tax and gross amounts.
- Depending on your country, VAT (or sales tax) on the deposit may become due as soon as it is received, not when the job is finished. Rates and timing rules vary by jurisdiction.
- When the sale completes, the final invoice shows the full amount and deducts the deposit already invoiced (net and tax) so nothing is charged or taxed twice.
A customer accepts your quote, but you want to lock in the order before you buy materials or start the work. That is exactly what a deposit is for, and in most tax systems it triggers an obligation: once you receive the money, you should issue a deposit invoice. Many freelancers and small businesses rush it or skip it altogether, even though it can commit tax and sets up the final bill. Here is how to create a deposit invoice properly: when to issue it, what it must include, how to work out the deposit and its tax, and how to settle it on the final invoice, with a worked example.
What is a deposit invoice, exactly?
A deposit invoice records a partial payment made by a customer before goods are delivered or a service is completed. A deposit is more than a goodwill gesture: unlike a fully refundable holding payment, it usually commits both sides. The customer commits to buy, and the supplier commits to deliver. It is a genuine accounting document, not a placeholder.
The quote is accepted
The customer approves the quote and pays a deposit (often 30% or 50% of the total).
You invoice the deposit
On receipt, you issue a deposit invoice that records the payment and any tax on it.
You settle at the end
On delivery, the final invoice shows the full total and deducts the deposit already invoiced.
Do not confuse it with a quote or a proforma invoice, which carries no accounting value and records no payment. A deposit invoice, by contrast, is a real invoice: it sits in your invoice numbering, enters your books and, where applicable, can trigger a tax point.
In one line
A deposit invoice turns a promise to buy into a firm commitment and, in many countries, creates a tax point on the amount already received.
When should you issue a deposit invoice?
The principle is simple: as soon as you receive a deposit, you should issue a deposit invoice. In most VAT and sales-tax systems, an advance payment received before the sale is complete is an event you must document. The invoice is normally raised at or shortly after the moment the deposit is received, and many tax authorities set a fixed deadline (for example, a set number of days after the payment or the tax point).
This applies whether your customer is a business or a private individual, as long as you are a registered supplier. It generally holds regardless of the deposit amount and regardless of whether you are selling goods or services.
Good habit
Put the deposit terms straight into the quote (amount or percentage, due date). The customer knows what to expect, and all you have to do is generate the deposit invoice once the payment lands.
Exact rules differ from one country to the next, so if you trade across borders or handle exempt and zero-rated supplies, check your national tax authority (for example, HMRC in the UK) or your accountant before you settle on a process.
What must a deposit invoice include?
A deposit invoice carries the same core details as a standard invoice, plus a few of its own. Here is the checklist, though the precise mandatory fields depend on your country’s invoicing rules:
| Detail | Why it matters |
|---|---|
| “Deposit invoice” | The nature of the document should be clearly stated |
| Invoice number | Unique, sequential and chronological, in the same series as your other invoices |
| Issue date | And, where relevant, the date the deposit was received |
| Supplier details | Business name, address, registration number and VAT/tax number where applicable |
| Customer details | Name or business name and address |
| Reference to the quote | The original quote or purchase order number |
| Description | The nature of the goods or service concerned |
| Deposit amount | The net base, the tax rate, the tax amount and the gross total of the deposit |
| Payment terms | Due date and any late-payment terms that apply in your country |
Requirements vary by jurisdiction, indicative for July 2026. In the UK, VAT-registered businesses must follow HMRC invoice rules; if you are not registered for VAT (for example under a small-business threshold), you invoice the deposit without VAT. Always confirm your local rules.
Do not skip this
A deposit invoice does not have to spell out final quantities and unit prices you do not yet know, but if you charge tax it must show the tax on the deposit. A deposit invoice with no tax breakdown can be non-compliant and can deny your customer the right to reclaim input tax.
How do you calculate the deposit and its VAT?
The calculation happens in two steps. First the deposit amount, then the tax that applies to it. The deposit is usually expressed as a percentage of the order total. You can apply it to the net or the gross figure, but stay consistent throughout.
Deposit (net) = total net amount × deposit percentage
Once you know the net base of the deposit, the tax is calculated as on any invoice, using the rate that matches the goods or service:
Deposit tax = deposit (net) × tax rate
VAT and sales-tax rates differ widely by country, and some products or services attract reduced or zero rates. Whatever the rate, the key point is the same: the tax on the deposit applies only to the deposit, never to the full order value. If you take 30% of the price up front, you charge tax on that 30% only. Check your national rate with your tax authority rather than assuming a figure.

Why can the tax on a deposit fall due immediately?
This is the most misunderstood part. In many VAT systems, receiving a deposit creates a tax point, meaning the tax can become due as soon as the money reaches your account. You may then have to account for it in the period in which you received the deposit, even though the work is not finished.
The timing rules are not identical everywhere, and they can differ between goods and services or depending on your VAT accounting scheme (for example, standard accounting versus cash accounting in the UK). The safe default is to assume a deposit can trigger tax on receipt, then confirm the exact treatment for your country and scheme.
Worth remembering
Receive a deposit in December, deliver in February: under a receipt-based tax point, the tax on the deposit is accounted for in December. What counts is the payment, not the delivery date. Confirm the rule that applies to you.
For a VAT-registered customer, the mechanism is symmetrical: they can usually reclaim the tax on the deposit once they pay it, provided they hold a proper deposit invoice. That is exactly why the tax must be shown correctly.
A worked deposit invoice example
Take a simple case to walk through the whole cycle. An agency signs a service quote for £2,000 net, at an illustrative 20% VAT rate, so £2,400 gross. The quote calls for a 30% deposit on order.
| Stage | Net | VAT (20% illustrative) | Gross |
|---|---|---|---|
| Quote total | £2,000 | £400 | £2,400 |
| Deposit invoice (30%) | £600 | £120 | £720 |
| Final invoice (balance) | £1,400 | £280 | £1,680 |
On signing, the agency receives £720 and issues a deposit invoice for £600 net + £120 VAT = £720 gross. Under a receipt-based tax point, that £120 is accounted for in the period the deposit is received. On delivery, the final invoice shows the full total and deducts the deposit: balance due £1,400 net + £280 VAT = £1,680 gross. Added together, the two documents come to exactly £2,000 net and £400 VAT, no more and no less. The 20% rate here is purely illustrative; use your own country’s rate.
No double counting, no missed tax
Good software chains quote, deposit and final invoice and reconciles the tax on its own. See which ones in our selection.
How do you settle the deposit on the final invoice?
The final invoice (or closing invoice) is issued once the goods are delivered or the service is complete. It does not simply bill “the rest”: it restates the full order total, then deducts the deposit already invoiced, in both net and tax terms. That deduction is what stops the tax being charged twice.
In practice, the final invoice should:
- restate the full net, tax and gross of the order;
- show a “deposit already paid” line as a deduction, with its tax;
- explicitly cite the number and date of the deposit invoice concerned;
- display the balance due after the deposit is deducted.
Without that reference to the deposit invoice number, neither the tax authority nor your customer can tie the two documents together, and the tax risks being counted twice. It is the most common mistake on final invoices prepared by hand.
The classic error to avoid
Rebilling the full total on the final invoice without deducting the deposit charges the customer twice and over-declares your tax. The deposit deduction, net and tax, must always appear in black and white.
Should you create deposit invoices by hand?
For a one-off deposit, a well-filled invoice template will do. But as soon as you chain quotes, multiple deposits and final invoices, manual handling multiplies the risks: a missing “Deposit invoice” label, tax calculated on the total instead of the deposit, a deposit not deducted on the final invoice, a broken number sequence. Each one weakens your books and can expose you at audit.
Invoicing software turns an accepted quote into a deposit invoice in one click, applies the correct tax rate, records it at the right time and generates the final invoice with the deposit deducted automatically. The stakes rise further with electronic invoicing, which more and more countries are phasing in on their own timetables. A tool connected to a compliant platform handles deposits, balances and local requirements without re-keying. Check the rollout dates that apply in your country.

Frequently asked questions
Is a deposit invoice mandatory?
In most tax systems, yes. As soon as a registered supplier receives a deposit before delivery or completion, they should issue a deposit invoice, whatever the amount. The exact requirements and any exemptions vary by country, so check your national rules, for example HMRC in the UK.
How do you calculate VAT on a deposit?
The tax on a deposit is calculated on the net deposit amount only, using the rate for the goods or service: deposit net × rate. For a £600 net deposit at an illustrative 20% rate, the VAT is £600 × 0.20 = £120. It never applies to the full order value, and the correct rate depends on your country.
When is the tax on a deposit due?
In many VAT systems, receiving a deposit creates a tax point, so the tax becomes due when the money is received rather than when the job is finished. Timing can differ by country and by accounting scheme, so confirm the rule that applies to you.
How do you deduct the deposit on the final invoice?
The final invoice restates the full net, tax and gross of the order, then deducts the deposit already invoiced (net and tax) on a dedicated line. It should cite the number and date of the deposit invoice and show the balance due after deduction, so the tax is not counted twice.
Do you add VAT to a deposit invoice if you are not VAT registered?
Only if you are registered for VAT (or the equivalent) in your country. If you trade below a registration threshold or are otherwise not registered, you invoice the deposit without VAT and note that no tax applies. Once registered, you charge tax on the deposit like any registered business.
